So I meant to do this (what I think is) cool background, shade the horse, and then color it in. Like any normal person would do... But it turns out, after taking a long time on the background and the shading (which, I've never tried before), I figured out I had totally messed up the layers and wouldn't be able to color it in.
Verdict: for never before previously having been successful at shading or backgrounds, I think this turned out pretty cool. But it kinda sucks that I can't color it in.
I will try again.
